Abstract
Within a method for predicting customer satisfaction for a transportation vehicle there is measured for the transportation vehicle a Noise, Vibration and Harshness (NVH) level within the transportation vehicle when an engine which powers the transportation vehicle is operating at wide open throttle. The method further provides for determining a customer satisfaction value for a specific transportation vehicle by means of interpolation or extrapolation from an existing correlation for a group of transportation vehicles within the same class. Such a correlation is obtained employing a Transformed Gamma Distribution (TGD) model or an aggregate combination of Transformed Gamma Distribution (TGD) models.
